Device and method for deploying an elongated hollow body in the coiled state

摘要

The invention relates to a device for deploying an elongated hollow body having: at least one elongated hollow body comprising two elongated shell half-bodies (2a, 2b) and for the first end a root, a mandrel (13) mounted rotary, on which the at least one elongated hollow body is, in a first state, wound up and compressed, and in a second state, unwound and deployed, so that an elongated cavity (4) is formed between the two halves body, the first half body is attached to the rotary mandrel in the root area, an expansion mechanism being engaged with the second half body in the root area, and pushes the second half body away from the rotary mandrel , in order to ensure the expansion of the cross section of the at least one elongated hollow body in said zone, when the latter is unwound from the rotary mandrel.
